My invention relates to a method and apparatus for assembling diamonds around t e riphery of a dressing wheel such as used hit trimmin the o erative surfaces of a grinder, and as for its principal purpose to afiorda way of securing a series of spaced diamonds in place with their outermost or operative points at uniform distances from the centeror rotary axis of the wheel on which they are mounted.

The-invention has for a further purpose 7 toprovide a practical mechanism by means of which a series of diamonds can be readily positioned and secured in placein proper-relationship to the dressing wheel. f

With these ends in view, the invention comprises the structure that will be clearly understood from the following description, when read in conjunction with the'a'ccompanying drawings, the novel features being pointed out in the claims following the dc.- scription. I

In the drawings;

Fig. 3 is a plan'view of the parts illus trated in Fig. 2. I Fig. dis a partial enlarged horizontal sectional view.

.art ofjthedressing wheel, a carrier suc as as isclosed in my copending application Serial Number 736,095 filed September 5, 1924, k

and designated at 1. Carrier 1 includes radi- ,allyextending tubular diamond retainers 2 which-tare split at 3, or otherwise provided -with openings in their side walls to admit the binding material.

. To position the diamonds, the carrier is inserted-on a pin 4 within an openin 5 1 and held manually with the tubular re ain- .ers 2 in line with a shoulder or flange 7 on a the holder The shoulder 7 has an opening 8 through which spring 9 and diamond 10 are successively inserted into each tubular retainer 2. As each diamond isinserted ,ing wheel illustrated'in my against the action of a sprin the carrier is rotated to brin place by the shoulthe next tu ular retainer opposite the openlng the previouslyinse'rtr e e ated until all the ing' 5, being guided and centered by-pm 4,

. unt-il it assumes the position of Fig. 1. With the parts in this position the circular wall 11'- bounding the opening 5 serves to limit the outward movement of the diamonds under the action of springs 9, and thus maintains the diamonds with their outermost points spaced equally and uniformly from the center or axis of the carrier 1.

Following this, the conductor 12' is positioned on the holder 6, the conductor 12 being provided with passages 13 leading from the to thereof to the opening 5. A suitable bin er such as type metal may then "be flowed' into the passages 13, filling the opening 5 in and around the tubular retainers, and imbedding the springs 9 and allbu't the operative points of diamonds 10, so that the latter are heldrigidly in their predetermined position, as fixed by springs 9 and circular wall 11. When the type metal or other binder has hardened, the conductor 12 is removed and likewise'the carrier 1. The walls of the latter may .then

be cut away as illustrated in Fig. 5 and'th carrier is ready for use as part of the dressco-pending apphcation referred to above.- f 1 v The invention may be carried out in other ways than that particularly described. and wherever it is desirable to secure a series of diamond points or analogous elements in a redetermined and uniform relation. on a arrier, and this application is intended to cover any other a aptations or departures as may come within the intent of my improvement or the scope of the following claims.

I'claim:

1. Mechanism for assembling diamonds or analogous elements around the periphery of a carrier comprising a holder having an opening to receive the carrier, a circular wall to limit the outward movements of and position the diamonds arranged in the carrier, said circular wall terminating in a shoulder having an opening through which the diamonds are successively inserted into the carrier, and means whereby a binder can be flowed into said opening into and around the carrier to retain the diamonds in prepen ent retainers arranged radially, a fixed circular wall surroundin the carrier, and a coil spring in each radia retainer for holding a diamond yieldably against said wall.

3. Mechanism for assembling diamonds about the periphery of a dressing wheel comprising a circular carrier having radial retainers, a fixed circular wall surrounding the carrier, and means for holding diamonds in said radial retainers in yieldable'contact with the wall.

4. Mechanism for assembling diamonds about the periphery of a circular carrier comprising a holder having a circular open- I upon the holder and having 0 enings communicating with the opening in the holder to convey a binder thereto.

5. Mechanism for assembling diamonds about the periphery of a circular carrier comprising a holder havinga circular opening to receive the carrier, a vertical carrier supporting pin arranged centrally of the openin a circular wall to define the position 0 diamonds arranged in the carrier, and a conductor. positionable upon the holder and having openings communicating with the opening in the holder to convey a binding material thereto.

In witness whereof, I have hereunto 40 signed my name. 4
